Identifying Some Ideal Molds 308334 & 320366

[SoonerEd]

I've picked up two new to me molds this past weekend.

They are marked Ideal, Middlefield without any vent lines. So, per the research on this website these appear to have been made on or before the mid 1950's. I'm trying to get some information on these molds as I can't find them in the resources I've found on this website for Ideal/Lyman molds.

308334: I can't find this one but I did find a mold number of 311334 that looks the same. Would these be the same mold but likely just numbered with the actual diameter instead of .308? The mold does drop at .311. Also, would the top punch for a 311334 be appropriate for this mold since the 334 is the same?

320-366: I can't find this one but I did find a mold number of 323366 that looks the same. Would these be the same mold but likely just numbered with the .323 diameter? Not sure what the mold drops at as I haven't cast with it yet. Also, would the top punch for a 323366 be appropriate for this mold since the 366 is the same?

Thanks.

Yes they are both the same as the later 311 and 323 versions.

Greetings,

The nose (bore riding) diameter may be different between the 308334 and 311334.

Cheers,

Thanks.

Was casting some Lyman 457124 bullets and decided to cast a few with these molds to check diameter.

The 308-334 is casting at .311 with RL
The 320-366 is casting at .324 with RL

My 308334 SC cast at .313/.298 and is one of my most accurate boolits. Works well in springfields and sized down in the Swiss rifles.

Paid $20 each for them. So looks like I might get some use from them in my 1903A and 8mm Mauser.
